哈德森:如何在一篇成功的文章之后发布这个xml?

我用firefox的Poster插件发送了一个xml帖子。这是从成功发布到hudson服务器中捕获的HTTP头。我正在尝试使用header()函数在php中复制此内容。

POST /createItem?name=tellme HTTP/1.1

这是我的php代码:

<?php


$data = file_get_contents("config.xml");

$post_data = $data;
$content_length = strlen($post_data);

header('POST /createItem?name=friends HTTP/1.1');
header('Host: somewhere.com');
header('Keep-Alive: 115');
header('Connection: keep-alive');
header('Content-type: text/xml');
header('Content-length: ' . trim($content_length));
header($post_data);

exit();

php代码失败并抛出: Warning: Header may not contain more than a single header, new line detected. Line 18.
